Late onset/Acquired/Regressive autism
Vaccine autism proven

[MMR is scheduled at around 12 and 15 months (see Schedule).  Pretty obvious red flag for vaccine autism yet suppressed, showing the power of State/Corporate medicine.  Now they deny it even exists.]

Quotes
"They claim that autism naturally occurs at about 18 months, when the MMR is routinely given, so the association is merely coincidental and not causal.  But the onset of autism at 18 months is a recent  development.  Autism starting at 18 months rose very sharply in the mid-1980s, when the MMR vaccine came into wide use.  A coincidence?  Hardly!"--Dr Rimland

The blind men can’t answer these questions: if autism is a genetic illness, why is the incidence increasing so dramatically? If autism is a behavior disorder, why do the children have chronic bowel problems? Why do they have ear infections, frequent viral infections, and eczema? Why do they have nutritional deficiencies? And why do most autistic children seem to develop normally and then start to regress? These are questions that can’t be answered by their theories. AUTISM: THE EVOLUTION OF A DISEASE by Bryan Jepson, MD

The “classic” form of autism was first described by Dr. Leo Kanner. These children were different from normally-developing children from birth.         However, a very different form of autism, formerly a minority variant, has now begun to predominate. In this, children develop normally, passing all their developmental milestones, and then later acquire an autistic-like condition. They lose their previously-demonstrated speech, learned behaviour and social skills. In effect, they dissolve into a state of mental impairment, of varying severity. Often the damage is severe or very severe, and usually the damage appears to be permanent, although some remedial treatments are claimed to be able to reverse some aspects of damage to a modest degree.
     This late onset of autism typically follows the receipt of MMR vaccination, but also appears to sometimes follow measles-containing vaccines such as monovalent (so-called “single”) vaccine, or measles-rubella (MR) vaccine, and sometimes other vaccines such as DPT (diptheria-pertussis-tetanus). ......No cases are known, at least to campaigning parents, of any children who have rapidly become autistic just before MMR or thimerosal-containing vaccines. This clearly implies that such cases are much fewer in number.

[2011 Jan] Why Don’t Children Regress Before They Turn One? by F. Edward Yazbak, MD, FAAP  Worried about vaccination being blamed for Regressive Autism, the health authorities and vaccine promoters quickly circulated the idea that autism, supposedly a purely “genetic disorder”, manifested itself between 18 and 24 months of age. In time, that somewhat preposterous idea became an accepted scientific fact, even though the syndrome was originally called “Infantile Autism” or “Kanner’s Infantile Autism” and an infant is, by definition, a child under the age of 12 months......So why don’t any of those little ones ever regress - really, really regress - at 11 months of age and why do they all wait and regress all together, just after their first birthday and their “one-year” check-up whether they are in the United States, the United Kingdom, Israel, Egypt or Australia?  Why don’t we ever, ever hear of babies regressing into autism during the vaccine break period, between 6 and 12 months of age or more specifically between age 9 and 12 months, when they are doing all those wonderful exciting things we need to call the neighbors, friends and family to witness or quickly find the movie camera to record? WHY, WHY, WHY DON’T BABIES REGRESS BEFORE THEIR ONE-YEAR CHECK-UP? 

I would also be particularly interested to learn of any documented cases of completely unvaccinated children who have later dramatically and inexplicably regressed into autism after a normal infancy. To date, no such case has ever been identified to me.

And this is regressive autism; it's not from birth. It happens sometimes within two days or a week. When the parents come in, the histories are so similar. We try not to suggest anything when we're taking a history. We just say, "What happened? What did you find? Did the child develop normally?" And the mother will say, "Yes, until..." and we know what she is going to say next: "...until some vaccine was given around 15 to 18 months." Doctors used to give the MMR on the same day as the DTP and the Hib, and that was usually the time the regression started. They've now shifted the schedule--the MMR is being given at 12 months.

There is a direct correlation between the increase in autism cases and the time that the MMR triple vaccine was introduced.  http://www.voicesofsafety.com/ph/v502a/research/
